LOOM.

To all 'whom t concern.'

Be it known that l, Eznnmn J. WILSON, a citizen of the United States, residing at East Greenbush, in the county of Rensselaer and State of New York, have invented cer# tain new and useful improvements in Looms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to looms and more particularly to lay actuating mechanism which is well adapted for actuating the lay of extremely broad looms such, for instance, as are adapted for the weaving of endless felts for paper making machines.

The lays of looms of the above type may be thirty to forty feet and more in length and the object of the present invention is to provide a simple and efficient mechanism which is well adapted for uniformly and accurately reciprocating lays of such length. To this end the invention comprises the features of construction and combination o parts hereinafter described and referred to in the claims.

A preferred form of the invention is shown in the accompanying drawings in which Fig. 1 is a plan view showing the lay base and the mechanism for oscillatingr the lay; Fig. 2 is a transverse sectional view; and Fig. 3 is a front elevation of a part of the layY actuating mechanism.

As shown in the drawings the lay actuating mechanism comprises an actuating bar 2, which is arranged parallel to the lay bed 4 and is arranged over the breast beam 6 and below the breast plate 8. The bar is connected with the lay at frequent intervals by bell crank levers 10, which are pivotally supported by brackets 12 secured to the upper side of the breast beam and are connected with the lay through links 14. Through the bell crank levers and links to and fro movements are transmitted from the actuating bar to the lay and the actuating force is applied to the lay at frequent intervals throughout its length. The bar 2 is moved in a direction to impart to lthe lay its beating up movement by a cam 16 se- Specication of Letters Patent.

cured to the cam shaft 18 and engaging a roll 2Q carried by a lever 22, the upper end of which is connected by a link 24 with the end of the bar. A heavy spring 26 is connected to the bar and to a bracket 28 secured to the breast beam and acts to hold the roll in engagement with the cam and to move the bar in a direction to give the lay its return movement. ln order that each connection between the actuating bar and lay may exert a pull upon the lay during its beating up movement, thus insuring a uniformly accurate and proper movement of the lay even when of extreme length, the links are made in sections which are oppositely screw-threaded and connected .by turnbuckles 30 so that the effective lengths of the links may be adjusted in setting up the actuating mechanism or to compensate for any inequalities of wear during continued operation of the loom.

While it is preferred to employ the specie construction and arrangement of parts shown and described, owing to its simplicity f and the ease and convenience with which it may be inspected, adjusted, or repaired, it will be understood that this construction and arrangement is not essential to the broader features of the invention and may be varied or modified as found desirable or best suited to the construction and mode of operation of the loom in which the invention is to be embodied.

What is claimed is:

1. A loom having, in combination, a lay,

an endwise reciprocating actuating bar arranged parallel to the lay, and a series of connections between the bar and lay for transmitting to and fro movements to the lay from the bar.

, 2. A loom having, in combination, a lay, a reciprocating actuating bar parallel to the lay, a series of bell crank levers connecting the bar to the lay at intervals throughout its length and through which t0 and fro movements are transmitted to the lay from the bar.

3. A loom having, in combination, a lay, a series of levers connected to the lay at intervals throughout its length, a common actuator connected with the levers to trans- Cir 5. A. loom, having, in combination, a lay,

a series of bell crank levers, adjustable links l0 connecting the levers With the lay at intervals throughout its length, and an enclvvise movable actuating bai` for rocking the levers to impart to the lay its beating up movement.
